Patented Nov. 22, 1932 PATENT OFFICE EMIL MARIUS ERIKSEN, OF BESSERUD,NEAR OSLO, NORWAY SKI Application filed September 22, 1930, Serial No.483,437, and in Norway September 27, 1929.

Skis which are to be used for distance runs are made as narrow aspossible in order to reduce their weight. This causes, however, somedifficulties as regards the securing of the toe irons of the tie becausethe fastening screws will have to be placed so near to the edges of theski, that sai-d' screws are liable to cause splits or cracks in the ski.A further drawback in such skis is that the middle 0 portion thereof isliable to be bent downwardly when in use, so that the ski, as iscommonly said, digs or burro-ws into the snow.

The present invention aims at removing said drawbacks. According to theinvention the ski is provided at each side of the portion where the tieis to be placed, with projecting Side parts which provide an increase ofthe material in which the securing screws are to be inserted and at thesame time increase the carrying surface of the ski, so that the saiddigging action is counteracted.

Said projecting side parts may, according to the invention, consist ofseparate battens which are in a suitable way secured to the ski proper.Thus no blank of greater size than usual is necessary for the properski, and if desired the battens may be used on common skis already onthe market.

The annexed drawingr illustrates by way of example some embodiments ofthe invention.

Figs. l and 2 are a side view and a top view respectively of the middleportion of a ski according to the invention.

Figs. 3 and 4 are similar views of a modified embodiment.

Fig. 5 illustrates a section on line V-V in Fig. l and Fig. 6 a sectionon line VI-VI in Fig. 3.

In Figs. l, 2 and 5 the ski is at each side provided with an enlargementor projection 2. Said projections extend along the ski substantially thelength of the ski runners foot, backwardly from a point somewhat infront of the place where the toe irons are secured to the ski. At thefront and rear ends said enlargements are inclined, so that they do notoppose the movement of the ski through the snow to any substantialdegree. A preferred cross section of said enlargements is illustrated atFig. 5, but obviously other cross sectional shapes thereof may be usedif desired, thus the side thereof may be straight or concave.

Figs. 3, 4 and 6 illustrate a modified embodiment of the invention,where the enlargements 2 consist of separate battens which are securedto the ski l proper in a suitable way,

for instance by means of screws 5 as illustrat- 60 preferably are of athickness equal to that of the rubber layer 8 usually used on skis.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed I declare thatwhat I claim is:

l. A ski comprising a runner having upright longitudinal sides providedwith a protruding portion on each side to form a broad foot support,each protruding portion being flush with the top of the runner along itsupper surface and tapered inwardly towards its lower edge to meet theupright side of the runner along a line spaced substantially above thelower edge of the runner, the protruding portions being further taperedat the-ir opposite ends to meet the sides of the runner.

2. A ski, as claimed in claim l, in which said protruding portions aresubstantially triangular in cross section.

3. A ski, as claimed in claim l, in which said protruding portionsconsist of separate battens secured to the ski proper.

4. A ski, as claimed in claim 1, in which said protruding portionsconsist of separate battens secured to the ski proper, said battensbeing provided with flaps secured t0 the ski.

In testimony whereof I affix my signature.

EMIL MARIUS ERIKSEN.
